She wasn’t even aware of the massive milestone until after creating her 17th album.
“When I saw the sticker on the front of my album saying ‘celebrating 50 years in the business’ I was like ‘what the...? That’s incredible’.”
Now 67, she is rather astounded by her longevity as an artist and she’s also pinching herself over the fact the likes of Sir Cliff Richard and Sir Rod Stewart wanted to work with her on her new album.
Having started her career as a singer in 1969, Tyler – who was born Gaynor Hopkins in Skewen, Wales – was discovered by a talent scout and scored a record deal in the mid-1970s.
She went on to release a number of albums, although it was her fifth release, 1983’s Faster Than the Speed of Night – a trans-Atlantic number one hit and Grammy-nominated effort – that made the raspy-voiced singer a household name with breakout hit single Total Eclipse Of The Heart.
Other hit songs followed, such as Holding Out For a Hero and A Rockin’ Good Way (To Mess Around and Fall In Love) with Shakin’ Stevens.
As much as she did not acknowledge her own landmark anniversary, Tyler also didn’t ever dream she’d be releasing album number 17, Between the Earth and the Stars.
It wasn’t even planned, she says. She thought that perhaps her 16th album, 2013’s Rocks And Honey, was her last.
Her speaking voice as distinctively husky as when she’s belting out one of her hits, she says: “I was only going to do three songs that a friend of mine wrote that I really loved.”
Tyler’s original plan was to record three new songs with David Mackay, who produced her first two albums in the late 1970s, and put them on a re-release of Rocks And Honey.
“But things just started happening – like it was fate, you know?” she adds.
One of those “things”, as she calls them, was the interest of Status Quo’s Francis Rossi, who was played the three new tracks by Mackay and was so entranced by them he suggested he and Tyler duet on a song called Someone’s Rockin’ Your Heart.
“It was good fun doing that with him – he’s a laugh a minute, he is,” Tyler says.
“There’s still some laughing kept on the track, because we were having such a good time in the studio.”
Tyler then shares how three musical giants – Sir Rod Stewart, Sir Barry Gibb and Sir Cliff Richard – got involved.
“David knew he would be meeting up with Sir Barry Gibb at Wimbledon and he asked him if he had a song for me,” Tyler says.
“A couple of months later, a beautiful song came in from Sir Barry, Seven Waves Away, which made it on to the album.”
“And then,” she continues, settling into her story, “I had an opportunity to do a duet with Sir Rod Stewart. It’s always been a dream of mine.”
Tyler, who has previously been dubbed the “female Rod Stewart” due to her throaty vocals, says she emailed Sir Rod after being encouraged by a friend of his she met on holiday in Barbados.
She recounts: “I was waiting for the right song and then a track called Battle of the Sexes came around.
“I emailed Rod, asking if he’d listen to the song, and he came back personally to me a few days later telling me he loved it.”
Then there’s the song with Sir Cliff, a dear friend.
“We both have houses in Portugal and he was at my house before we were going out for dinner with friends,” Tyler says.
“I played him this collection of songs and he was like, ‘Wow Bonnie, this is fantastic – let’s do a duet’.
“We got the right song, Taking Control, and he loved it on the very first listen.”
“I can’t believe they all wanted to work with me, it’s incredible,” she says.
“I feel blessed. To work with those guys.”
With the #MeToo movement in mind and the ongoing conversation around female representation, it’s difficult not to ask someone who has been in music for as long as she has for her take.
Has she ever had to fight her way through to be heard? Was it difficult for her to break through in a man’s world?
“Not really, no,” comes her simple reply.
“I think it’s because I’ve got this rock voice, you know? And I’ve had my fair share of headlining ... it’s been incredible. I’m not complaining.”
Bonnie Tyler’s Between the Earth and the Stars is out now.
